Hi all,I don't understand all of the computer mumbo jumbo when i look one these up. I just have some questions:First off, I'm talking about those little things you can put on a key chain and plug into a USB port...is that a flash drive?What are they for? I tried using one once to store some pics on and I can't find the pics. Can you store your actual stuff on there like more than just files or music or what? Can you put programs on them too?I just don't know anything about them. I am still catching up on all the computer stuff my laptop and phone can do and would like to understand the this to see if it is something I could really use. So, any help out there?Thanks,Gray
